Which of the following is listed as a type of jet engine?

• A. Turbofan
• B. Ramjet
• C. Turbojet
• D. Turboshaft

Answer: (B)

Jet engines come in several forms that create thrust by accelerating air through combustion. A ramjet is a simple, air-breathing jet engine that contains no compressor or turbine. It relies on the vehicle’s forward speed to compress incoming air, then heats and expands it in a combustion chamber to produce thrust. This lack of rotating machinery and its reliance on high speed to operate are distinctive traits that classify ramjet as a jet engine type. In contrast, turbofan and turbojet engines use compressors and turbines to manage airflow and drive thrust, while a turboshaft is designed primarily to produce shaft power to drive something like helicopter rotors rather than to produce jet thrust.
